Varieties of *-regular rings [PDF]

Mathematica Slovaca, 2019
Given a subdirectly irreducible *-regular ring R, we show that R is a homomorphic image of a regular *-subring of an ultraproduct of the (simple) eRe, e in the minimal ideal of R; moreover, R (with unit) is directly finite if all eRe are unit-regular ...

On Sπ Weakly Regular Rings, II [PDF]

Al-Rafidain Journal of Computer Sciences and Mathematics, 2010
The main purpose of this paper is to study right(left) Weakly regular rings. also we give some properties of Weakly regular rings, and the connection between such rings and CS-rings, MGP-rings and SSGP-rings.

On Weakly Regular Rings and SSF-rings [PDF]

Al-Rafidain Journal of Computer Sciences and Mathematics, 2006
In this work we consider weakly regular rings whose simple singular right R-Modules are flat. We also consider the condition (*): R satisfies L(a)Ír(a) for any aÎR. We prove that if R satisfies(*) and whose simple singular right R-module are flat, then Z

On sπ-Weakly Regular Rings [PDF]

Al-Rafidain Journal of Computer Sciences and Mathematics, 2008
A ring R is said to be right(left) sp-weakly regular if for each a Î R and a positive integer n,  aΠ aR aR (aÎ R aR a). In this paper, we continue to study sp-weakly regular rings due to R. D. Mahmood and A. M. Abdul-Jabbar [8].

A Generalization of Von Neumann Regular Rings [PDF]

Al-Rafidain Journal of Computer Sciences and Mathematics, 2009
In this paper, we introduce a new ring which is a generalization of Von Neumann  regular rings and we call it a centrally regular ring. Several properties of this ring are proved and we have extended many properties of regular rings to centrally regular ...

Comparison of symbolic and ordinary powers of ideals [PDF]

, 2002
In this paper we generalize the theorem of Ein-Lazarsfeld-Smith (concerning the behavior of symbolic powers of prime ideals in regular rings finitely generated over a field of characteristic 0) to arbitrary regular rings containing a field.

Rings in which Every Simple Right R-Module is Flat [PDF]

Al-Rafidain Journal of Computer Sciences and Mathematics, 2004
The objective of this paper is to initiate the study of rings in which each simple right R-module is flat, such rings will be called right SF-rings. Some important properties of right SF-rings are obtained.

On γ-Clean Rings

Science Journal of University of Zakho, 2017
In this paper we introduce the concept of -clean ring and we discuss some relations between - clean ring and other rings with explaining by some examples. Also, we give some basic properties of it.
